Salmonella enterica subsp. enterica strain NCTC6754

Salmonella enterica subsp. enterica strain NCTC6754 is a significant pathogen characterized by its Gram-negative, spirilla shape and microaerophilic oxygen requirement. This strain is classified as a chemoorganotroph, utilizing organic compounds for energy. It typically exists in chains or as single cells and possesses flagella, contributing to its motility, although it is noted as non-motile in practice. NCTC6754 is optimized for growth at 37°C and falls within the mesophilic temperature range. It has a unique cellular structure comprising two membranes and a single replicon. The strain is free-living, indicating its ability to survive outside of host organisms, while also being host-associated, primarily affecting a broad range of hosts including Homo sapiens (humans), Gallus gallus (chickens), and various plant species such as Solanum lycopersicum (tomato) and Arabidopsis. This strain is known to cause a variety of health effects in humans, including bacteremia, acute cholecystitis, and systemic infections such as Salmonellosis, which can lead to symptoms like diarrhea and gastroenteritis. Its potential for causing food poisoning highlights its relevance in food safety and public health. The ecological insight drawn from the presence of multiple hosts suggests that S. enterica subsp. enterica strain NCTC6754 plays a role in interconnected ecosystems, affecting both animal and plant health, and underlines the importance of monitoring this pathogen in agricultural and clinical settings.
